But what I cannot remember is-whether taking BO requires the progesterone cream as well? Is BO estrogenic? I know for sure herbs are.

I would like to know that, too. I've heard some people say that BO (or BB, at least) is progesterone based, but there was no conclusive reasoning behind that that I saw.

You need to make sure your body temperature is at a certain range otherwise NBE wouldn't work. Can someone please advise me how to take my body temperature accurately and what the right temperature should be?

You use your basal body temperature. If you google that, there are lots of sites detailing how to take it. Basically, you want to take your temperature first thing in the morning right after you wake up. Keep the thermometer next to your bed because you want to move as little as possible before you take your temperature. I think you might need to take the temperature at the same time every day, but I'm not sure. Some sites also say that you should use a fertility thermometer because it's more accurate and sensitive. I think you should aim for a temperature over 98 degrees F, but it might vary from person to person.

Good luck!
